Figure 4: Subcutaneous temperature in 2 cm depth of tissue on the postoperative days 2 and 10 in the group with water-filtered infrared-A and visible light (wIRA(+VIS)) and in the control group with only visible light (VIS)
(given as minimum, percentiles of 25, median, percentiles of 75, and maximum (box and whiskers graph with the box representing the interquartile range); c.t.: confirmatory test (Mann-Whitney U test); adapted from [5]).
During irradiation with wIRA(+VIS) the subcutaneous temperature rose markedly by approximately 2.7°C, whereas it remained unchanged in the control group.
